To @ZZ whom it may concern:

Be it known that I, WILLIAM R. BAKER, of `Watertown, in the county ofJefferson, in the State of New York, have invented new and usefulImprovements in Water-Closet Flushing Devices, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

My invention relates to flushing devices for water'closets or sinks, andhas for its object to dispense with the tank or Servicebox and at thesame time furnish the after-Wash; and the further object is to providemeans for determining the length of time for the water to flow, or thequantity thereof during each operation of the device.

To this end mywinvention consists in the combination of a pipe orchamber closed at one end and connected at the other end with a supplypipe, an outletpipe communicating withone side of the. first mentionedpipe, a dash-pot formed stationary within the latter pipe at the closedend, a rod with a piston 4thereon entering the dash-pot, a valve on the25 rod to open and close the supply pipe, and means connected to the rodto move the same longitudinally in one direction against the action of aspring; and my invention consists in certain other combinations of partshereinat'ter described and specically set forth in the claims.

Referring to the drawings, Figure lis a side elevation of my improvedflushing device. Fig. 2 is a vertical longitudinal sectional view of thesame, with a side elevation of the piston-rod within the pipe; and Fig.3 is atrans` verse section on line :uw of Fig. l, looking from left toright of the figure.

In the said drawings, A represents the pipe which is shown extendinghorizontally, having one end closed by a cap a, or other suitable andwell known means. The cap is threaded on its inner side to engage thethread on the end of the pipe. On theinner side of this cap a,preferably integral with the same, as shown, is a dash-pot or tube, B,concentric with the pipe, A, but much smaller than the latter andprojecting from the cap a short distance.

Extending centrally and longitudinally within the pipe, A, is a rod, D,which may be said rod is secured a valve, C, formed preferably of aleather disk of less diameter-than the interior of the pipe. When thepistonrod, D, is forced to the right as far` as possi- A ble by theaction of the coil-spring, E, bearing with one end upon the valve, C, ora washer, of the same size in contact with the valve, and with its otherend upon a tlangef within the supply pipe, F, the supply of water isAcut off as the rim of the valve, G, is then in contact' with a flange orseat, c, on the inside of the pipe. When the supply is thus cut off orwhen the piston rod is in this position, the piston is in closeproximity to the cap 0. or to the bottom of the dash-pot B.

G is the outlet on the upper side of the pipe, A, and is connected by apipe with the water closet or sink to be flushed. On the opposite sideof the pipe, A, from the outlet, G, is formed a bearing, H', for arock-arm, H, which extends toward the rod, D, and being bifurcated lieson each side of the rod and in a re" cess in a block, e, secured to therod by set screws, e', e.

By means ofa spindle, h, extending through the said bearing and therock-arm, the rod, D, may be moved to the left against the action of thespring to allow the water to tlow around the valve, C, to and throughthe outlet G. The spindle has a square head and may be operated by alever thereon, as indicated in dotted lines in Fig. 3 ofthe drawings, orother suitable means. left, the piston rod is released and allowed toreturn to its original closed position by the action of the spring, E,alone.

It the piston, D', lits closely and is not provided with a valve oropening, the tube, B, forming the sides of the dash-pot is perforated byone or several holes, b, at different points along its length, so thatthe valve, C, will gradually return to its seat owing to the gradualiiow of water from the dash-pot through said holes that entered thedash-pot when the piston was moved to the left. The flow is con- Afterbeing moved to theV trolled or regulated by a screw, I, which passesthrough the side ofthe pipe or cap a and enters a small hole, t', at ornear the base of the dash-pot. By means of this screw the hole, i, maybe closed more or less todelay the return of the valve, C, to its seat,c, as long as may be necessary in order to flush the closet or sinksutliciently. By the proper adjustment of this screw, I, the flow ofWater maybe prolonged after the handle is released as long as desired.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The combination in a flushing device, of -a pipe closed at one endand connected at the other end with a supply pipe, an outlet to one sideof the first mentioned pipe, a dash-pot within and at the closed end ofsaid pipe, a piston in the dash-pot, a rod connecting the piston with avalve, the seat for the valve, a spring to move the rod and valve towardits seat, perforations in the side Walls of the dashpot, at dierentpoints along its length and suitable means to move the rod against theaction of the said spring, as set forth.

2. The combination in a flushing device, of a pipe closed at one end andconnected at the other end with a supply pipe, an outlet to one side ofthe first mentioned pipe, a dashpot within and at the closed end of saidpipe, a piston in the dash-pot, a rod connecting the piston with avalve, the seat for the valve, a spring to move the rod and valve towardits seat, perforations in the side walls ofthe dashpotat differentpoints along its length, a screw passing through the pipe and adapted tocloseV more or less the hole nearest the base of the dash-pot, andsuitable means to move the rod together with the piston and valveagainst the action of the coil spring, as set forth.

In testimony whereof I have hereunto signed my name.

WILLIAM R. BAKER.
